Wood affected by woodworm. Signs of woodworm usually consist of holes in the wooden item, with live infestations showing powder (faeces), known as frass, around the holes.. The size of the holes varies, but they are typically 1 to 1.5 millimetres (5 ⁄ 128 to 1 ⁄ 16 in) in diameter for the most common household species, although they can be much larger in the case of the house longhorn beet
The common furniture beetle or common house borer (Anobium punctatum) is a woodboring beetle originally from Europe [1] but now distributed worldwide. In the larval stage it bores in wood and feeds upon it. Adult Anobium punctatum measure 2.7–4.5 millimetres (0.11–0.18 in) in length.
Fragment of a broomstick affected by woodworm. Woodboring beetles are commonly detected a few years after new construction. The lumber supply may have contained wood infected with beetle eggs or larvae, and since beetle life cycles can be one or more years, several years may pass before the presence of beetles becomes noticeable.
Some such larvae exhibit a superficial resemblance to worms and are the likely inspiration for the term, though they are not true worms. In other cases, termites , carpenter ants , and woodboring beetles will first infest wooden bookshelves and later feed on books placed upon the shelves, attracted by the wood-pulp paper used in most commercial ...
Setae that are found on abdominal segments 1-6 assist in providing support as the larva leaves the egg and excavates the initial gallery. [6] The whitish-coloured larvae measure up to 70 millimetres (2.8 in) long and normally feed on dead wood of gymnosperms (mainly native and introduced conifers) associated with lowland podocarp forest.

The fall webworm (Hyphantria cunea) is a moth in the family Erebidae known principally for its larval stage, which creates the characteristic webbed nests on the tree limbs of a wide variety of hardwoods in the late summer and fall.
Its back has tiny bumps or dots, and its sides have a small edge. The back legs and the lower body have long white hairs. The front legs have three small teeth at the end, and the back legs have a bump on the outer edge. The bottom part of the legs have small bumps, and the very last part of the body is slightly curved, both in males and ...
